ELLENSBURG, Wash. -- A Morongo, Calif., man died when his motorcycle plunged off a cliffside trail this weekend, Kittitas County sheriff's officials said Monday.

David Olen, 62, was killed Saturday afternoon when he tumbled hundreds of feet from the trail on the north side of the summit of 6,245-foot Mount Clifty, 30 miles southwest of Ellensburg, Undersheriff Clay Myers said in a news release.

Olen was part of a group of experienced riders who were traveling from State Route 410 in Yakima County to their weekend camp in Cle Elum.

They topped the summit and had just started down the north side when Olen passed through a narrow part of the trail and lost his balance. Another rider told deputies that his right handlebar touched the cliff and his left leg was over open space.

The riders estimated Olen fell from 600 to 800 feet, cartwheeling and going over a vertical section of the rocky avalanche chute before coming to rest.

A Snohomish County sheriff's helicopter removed Olen's body Sunday.

Investigators say they consider the death accidental. No evidence of alcohol use or recklessness was found, Myers said.
